PRODUCTION DATA
Figure 2-34 shows the variation of ATQ_CNT as a function of motor supply voltage, with all other operating conditions remaining same.
When the VM_SCALE bit is configured to be 1b, the auto-torque algorithm automatically adjusts the ATQ_UL, ATQ_LL and ATQ_LRN parameters as per the supply voltage.
Figure 2-35 shows how the ATQ_LRN parameters automatically vary with the supply voltage when VM_SCALE bit is set to 1b.
